Sign Method
Creates a new CAdES signature over the provided data.
Syntax
cadessigner.sign(level, detached, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
Call this method to produce a new signature of the needed Level over the provided data. Set Detached to true to generate a detached signature (stored as a separate file and not including the data).
CAdES standard defines a number of different 'levels' of signatures. Supported signature levels:
| cslUnknown | 0 | Unknown signature level |
| cslBES | 1 | BES (Basic Electronic Signature) |
| cslEPES | 2 | EPES (Electronic Signature with an Explicit Policy) |
| cslT | 3 | T (Timestamped) |
| cslC | 4 | C (T with revocation references) |
| cslXType1 | 5 | X Type 1 (C with an ES-C timestamp) |
| cslXType2 | 6 | X Type 2 (C with a CertsAndCRLs timestamp) |
| cslXLType1 | 7 | XL Type 1 (C with revocation values and an ES-C timestamp) |
| cslXLType2 | 8 | XL Type 2 (C with revocation values and a CertsAndCRLs timestamp) |
| cslBaselineB | 9 | Baseline B (B-B, basic) |
| cslBaselineT | 10 | Baseline T (B-T, timestamped) |
| cslBaselineLT | 11 | Baseline LT (B-LT, long-term) |
| cslBaselineLTA | 12 | Baseline LTA (B-LTA, long-term with archived timestamp) |
| cslExtendedBES | 13 | Extended BES |
| cslExtendedEPES | 14 | Extended EPES |
| cslExtendedT | 15 | Extended T |
| cslExtendedC | 16 | Extended C |
| cslExtendedXType1 | 17 | Extended X Type 1 |
| cslExtendedXType2 | 18 | Extended X Type 2 |
| cslExtendedXLType1 | 19 | Extended XL Type 1 |
| cslExtendedXLType2 | 20 | Extended XL Type 2 |
| cslExtendedA | 21 | Extended A |
| cslA | 22 | A (archived) |
